This is even more true if you are the only person in the department. For the most part the guys here have been pretty flexible with my schedule as their network administrator which I greatly appreciate. However I do not believe it is due to them understanding the broad IT schedule, but instead just plainly not understanding my department at all.
Recently though one of the execs made a new policy effective immediately that basically required everyone to work the same hours and come in earlier. I right away knew this would cause conflict in my schedule. So I did my best to explain to him that being confined to 6-3 or something similar would make it difficult for me to finish my work.
Here are some of the reasons:
- A lot of maintenance work is done off-peak hours, for me later in the night from home
- Because of the above, I stay up later, one reason I come in at 9 instead of 6
- Regardless of the above two factors, I still get calls early in the morning or late in the evening for either staff still in the office or remote users
- I've worked holidays often
- I've worked during my vacation (really expected to)
That 1-2 hours of extra sleep is a big help, considering I am a night person anyway. After I reasoned with the exec and also appealed to my quality of work and also a little help of Jake Messersmith PhD: http://www.shrm.org/Education/hreducation/Documents/46-3%20Messersmith.pdf
I was able to convince him to let me keep control over my own schedule (within reason). So as it is, my schedule is the same still, basically 9 to 4:30, but it isn't a rigid shift either. I can decide to come in late, leave early or the opposite depending on work requirements for the day.
